LOS ANGELES (Reuters) - Wonder Woman star Lynda Carter returns to her superhero roots this week in the movie "Sky High" but she's got a new job: the stiletto-heeled, tough principal of a high school for kids with extraordinary powers.

The producers of the family-friendly Walt Disney Co. comedy, which opens on Friday, were ecstatic to get Carter, 54, best-remembered for her spin on 1970s television as Wonder Woman.

The actress, who has worked in over 50 projects since the series, admits to being tired of playing heroines and has often turned down roles that recalled her Wonder Woman past.

In the film, Carter dishes out lessons to aspiring crime-fighters as the dressed-to-kill principal who can also turn herself into a comet.
